Composite (light-cure) fillings use a tooth-coloured resin that is placed in layers and hardened with a special curing light. The material bonds directly to the tooth, which often allows the dentist to preserve more healthy tooth structure.
They are commonly used for cavities in front and back teeth, for repairing chips, and for replacing older fillings when a natural appearance is desired. Your dentist will advise if a composite is suitable for the size and position of your cavity.

Frequently Asked Questions

Composite can pick up stains over time from tea, coffee or smoking. Good hygiene and regular polishing help keep it looking natural.
The blue curing light is a standard dental tool and is used for a few seconds at a time. Your eyes can be protected with glasses during the procedure.
